Hi Allison,
Your mix sounds lovely. I do have a couple of questions though. First, I have heard that flax when exposed to frost can develop prussic acid, which is dangerous for horses. Does that apply to blue flax? We have two pastures, one we lease to a man for his horse, and the other is for the chickens and rabbits. I was only thinking of using your seed mixture in the chicken/rabbit pasture, but the horse pasture is right next to it on the downwind side? Would this be a problem?
Second question is regarding the yarrow. I seem to be very allergic to the variety in my garden. Whenever my skin comes in contact with it, I get itchy welts. Also, when put in the garden, the chickens turn up their beaks at the yarrow. Is it possible to have the mix without the yarrow? It is not a deal breaker, but I just thought I would ask. Thanks for your help. Julie
